The convergent polygynous mating systems of marine iguanas and otariid pinnipeds depend on the existence of large female aggregations. These can build up where abundant marine food resources occur around oceanic islands which harbour fewer predators than continental areas. For marine iguanas distribution of food resources appears to determine the location of colonies, while for pinnipeds habitat choice is more decisive. In marine iguanas females benefit from gregariousness through reduced… 
Female habitat choice as a determinant of the reproductive success of the territorial male marine iguana (Amblyrhynchus cristatus)

TLDR
A shift of females from one territory to another within one colony between two succeeding years was correlated with the change in relative weight of territory owners, interpreted as an indication of female choice.
Territory establishment in lekking marine iguanas, Amblyrhynchus cristatus: support for the hotshot mechanism
TLDR
Most male–male interactions served to distract successful males and may lead to spatial spillover of females into territories of unsuccessful males, which appears largely governed by hotshot processes in marine iguanas.
Male reproductive success and its behavioural correlates in a polygynous mammal, the Galápagos sea lion (Zalophus wollebaeki)
TLDR
Sexual dimorphism in Galápagos sea lions may be more influenced by selection for fasting than fighting ability, as several males gained relatively high reproductive success despite short attendance and hardly any involvement in agonistic interactions.
The evolution of reproductive systems in pinnipeds
TLDR
The question of why otariid females reproduce in dense clusters instead of behaving as their relatives, the phocid females, that rear their pups in isolation or in small groups is addressed.
The Galapagos sea lion: adaptation to spatial and temporal diversity of marine resources within the archipelago
TLDR
Time at the colony proves the best predictor of reproductive success, which reflects the long drawn-out reproductive season often lasting 6 months, and Juveniles need exceptionally long to become nutritionally independent.
Territory establishment in lelclcing marine iguanas, Amblyrhynchus cristatusr. support for tlie liotsliot meclianism
TLDR
In marine iguanas, territorial establishment appears largely governed by hotshot processes, and most male-male interactions served to distract successful males and may lead to spatial spillover of females into territories of unsuccessful males.
DISENTANGLING THE CONTRIBUTION OF SEXUAL SELECTION AND ECOLOGY TO THE EVOLUTION OF SIZE DIMORPHISM IN PINNIPEDS
TLDR
This study provides novel insights into the role of sexual selection for the coevolutionary dynamics of SSD and mating system and calls for the inclusion of ecological variables when studying sexual selection and argues for caution when assuming causality between coevolving traits.
Diversity of compounds in femoral secretions of Galápagos iguanas (genera: Amblyrhynchus and Conolophus), and their potential role in sexual communication in lek-mating marine iguanas (Amblyrhynchus cristatus)
TLDR
The diversity of the lipophilic fraction of males’ femoral gland secretions among 11 island populations of marine iguanas is described and the results indicated that 11-eicosenoic acid may play an important role in intraspecific chemical communication in marine iguanaas.
EARLY EVOLUTION OF SEXUAL DIMORPHISM AND POLYGYNY IN PINNIPEDIA
TLDR
Evidence for the early evolution of dimorphism within a model mammal group, the pinnipeds, is reported, and a close correlation between mating system and sex‐related cranialDimorphism is shown, and the ancestral mating system of extant pinnIPeds is reconstructed as highly polygynous.
Gregarious sexual segregation: the unusual social organization of the Malagasy narrow-striped mongoose (Mungotictis decemlineata)
TLDR
This study presents new detailed results on the sex-specific social organization of a previously unstudied endemic Malagasy carnivore, the narrow-striped mongoose, and evaluates the results in comparison to the closest related taxonomic group, the mongooses, in which long-term studies have contributed substantially to the recent development of theories.

  • 1972
TLDR
Observations on the Galapagos sea lion suggest that this may not hold for all polygynous pinnipeds, and that the bull of the California sea lion, Zalopkus californianus califORNianus, establishes a territory when breeding and excludes other males.

TLDR
The present paper undertakes to elaborate a verbal model based on ideas first suggested by Nutting (1891) and extended by Bertram (1940) and by Bartholomew (1952) and to place it more firmly in a documentable behavioral context.
Group Size and Polygamy in Social Mammals
TLDR
Comparative evidence shows that female survival and reproductive rates are influenced by group size, as required by the model, and several tentative hypotheses concerning male reproductive strategies for social mammals are proposed.

TLDR
The concept of homology can be successfully applied to all behavior characters, from insect courtship to human language, regardless of whether they are genetically fixed or are acquired through tradition, whether the information necessary to produce the homological characters has been genetically or traditionally transmitted.
